You are managing an Oracle Database 12c database. The database is open, and you plan to perform Recovery Manager (RMAN) backups. Which three statements are true about these backups? (Choose three.)
A.
The backups would be consistent.
B.
The backups would be possible only if the database is running in ARCHIVELOG mode.
C.
The backups need to be restored and the database has to be recovered in case of a media failure.
D.
The backups would be inconsistent.
E.
The backups by default consist of all the data blocks within the chosen files or the full database.
Why would B be correct? Backups using RMAN are in fact possible with the database in noarchivelog mode. However, the backups would be cold (offline) backups. We would only be able to restore the DB to the most previous backup but we can in fact take the backup.
I circled back to this because I was not certain I was correct. I verified with Oracle DB and you are correct. I should have paid more attention. Thanks.
A is not correct as the database must be shut down for backups to be consistent. The question states that the database is open.
